Gas analyzer for blending systems

Lehigh Valley, PA— Thermal Conductivity Detector (TCD) gas analyzer was developed for use with gas blending/mixing systems. TCD detects gas composition by measuring the difference in thermal conductivity between a reference gas stream and the sample gas stream. It uses a dual pass sampling system that allows easy analysis of a number of gas combinations.

Lehigh Valley, PA - Thermal Conductivity Detector (TCD) gas analyzer was developed for use with gas blending/mixing systems. TCD detects gas composition by measuring the difference in thermal conductivity between a reference gas stream and the sample gas stream. It uses a dual pass sampling system that allows easy analysis of a number of gas combinations. A five-way valve located in the front face of the analyzer simplifies the calibration process. Available output options include two or four relay output cards; RS-232/485 and DeviceNet communication cards; and 1-10 V or 4-20 mA. Operating rate is 0.5 scfh; minimum gas supply is 2-3 psi, maximum is 100 psig, and accuracy is 2% of span.
